Problem chmod single site

[Nova Web LTD]

I have a problem
I have a website that needs some files to 444
we put the file to 444, but the next day and was put by the system 644.
how can I ignore the control file only on this site?
thank you very much

Use chattr

chattr +i file.php

to protect it. Or find what process changes the file's permissions and stop it.
